http://www.game-art-hq.com/ is not a bad site for this type of information, since it organizes characters by name. https://en.wikipedia.org/wiki/Category:Video_game_characters_by_year_of_introduction also isn’t terrible but it sorts characters by last name instead of by their first, which might not be what you’re looking for.
